I just sold my LR launcher from Achilles coz its performance was not consistent enough for my needs. Sometimes I got 60 seconds spin time, sometimes 70.
With ripcords I simply pull hard without thinking about letting go and not slamming the launcher. And I get always the same spin time.
So for me its Riptide launcher first and Sword launcher second.
Probably czA launcher if you like string launchers or the dragon launcher (comes with Ace Dragon & Diabolos) if you prefer ripcord launchers. The new Master Diabolos comes with a black LR string launcher which seems to closely resemble the czA launcher. I’m expecting that to be a very good option as well.
Here’s a link to a dragon launcher if your looking for one. Good price and sold by a trusted seller, 3.style
